The value of USD vs other currencies. Noting of course the other currency values also change. Comparing August 2018 and today. USD vs the pound: 1:0.78 -> 1:0.74 = down 5% USD vs Yuan: 1:6.86 -> 1:6.36 = down 7% USD vs Euro: 1:0.86 -> 1:0.89 = up 3% USD vs CAD: 1:1.31 -> 1:1.28 = down 2.5% For inflation all these countries are targeting 2% annual inflation, so around 6-7% total inflation. So the most pessimistic view would seem to be USD vs Yuan and 7% from inflation, so maybe 14% comes from changes in "value"? Anyway, that's "only" ~$400 million :D
